DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals, respectively. The drawing figures might not be to scale and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.

In one exemplary embodiment of the present inventions, greater flexibility is provided for moderating localized conditions during a day and throughout the seasons. A given area of a building may change in temperature or lighting conditions over time, such as from changes in sunlight or changes in the use of machines. In this exemplary embodiment of the present inventions, localized areas can be provided with adjustable lighting, adjustable fan speeds, or other environmental modifiers. This control can help to support the environmental needs of workers or patrons in restaurants or bars.

In another exemplary embodiment of the present inventions, lighting and cooling conditions in residential applications can be more accurately controlled. For example, owners of older homes that have lower ceilings will not be able to use a traditional ceiling fan with an attached light fixture, as such units often hang too low for tall people, creating a safety issue, and may not cool the entire room evenly or well. In this exemplary embodiment, homeowners can choose to have multiple smaller fans that better cool the room, and disperse heat throughout the room, and multiple lights that better light the room, all with the added flexibility of being able to choose which lights or fans to have on and to vary the power to each.

Existing track fixtures can also be accommodated using the present inventions. In one exemplary embodiment of the present inventions of FIG. 1, a remote controller 4 individually controls several track fixtures such as track fans 2 and track lights 3, which are attached to a ceiling mounted track 1 such as Halo™ track using standard connectors 5 or 6. The track fans 2 and track lights 3 are controlled by signals transmitted from the transmitter in the remote control 4. The signal frequency is adjusted by the electronically programmable memory unit in the remote control 4 to adjust the signal frequency of track-system receivers for each track fan 2 and each track light 3. The track 1 has one circuit and its power source is from the outlet box in the ceiling.

Each track fan 2 moves air with a suitable motor, turning short, soft blades. For selected environments such as a low ceiling room or low illumination area, the blades can have a safety LED light on the blades, visible when the blades are rotating. The air movement from the fans can be aimed in different directions by adjustment of forked metal support arms 25 as shown in FIGS. 2 and 3, or using 360°-horizontal swivel stem 24, to control direction of the fan within 300° of vertical space and 360° of horizontal space. The track light fixtures 3 aim illumination in desired directions by adjustment of their swivel stems 24 or forked metal support arms 25 and gimbals 29 or light heads 32 as shown in FIGS. 6 and 7. The track light fixtures have Edison-base or other sockets and are using energy efficient compact fluorescent or LED bulbs, or incandescent bulbs.

In accordance with another exemplary embodiment of the inventions, the remote control 4 can be provided with a programmable selector 1402 and a programmable controller 1404 that are used to set frequencies, data or other controls for predetermined track fans or track lights. Associated controllers in each of the track fans and track lights can be automatically or manually set to match a setting of the controller. Alternatively, a universal controller can be used with pre-existing track fixtures to allow existing equipment to be upgraded to provide additional functionality. The controllers can be set accommodate desired groupings of track fixtures. For example, all track lights and track fans could have the same controller setting, each track light could be set to a separate controller setting to allow individual illumination adjustments, or other suitable combinations can also or alternatively be used. The controller settings can be used to determine the signal frequency transmitted to the track fans and track lights as previously described.

In another exemplary embodiment of the present inventions, the track fans and track lights are temporarily and/or permanently attached to a variety of fixture types, including but not limited to track, rail, and cable lighting fixtures, a single light fixture canopy, a recessed lighting can, a sconce, and a wall fixture. These variations (a) accommodate existing fixtures to reduce the costs of electrical and construction modifications in buildings and (b) bring the air movement and/or illumination closer to people's work or relaxation areas, for example, directly over a couch, a bar or a desk.

In another exemplary embodiment of the present inventions, one or more of the track fans and/or track lights do not include the track-system receiver as an integral part and so are attached to a track-system receiver device that is attached to a track. The attachment is via standard connectors. The track-system receiver device is set to the appropriate frequency by use of the electronically programmable memory unit or by automatically or manually setting its controller.

The track can also be attached to a ceiling or wall in an area that does not have an existing power source so an electric supply with cord 6 in FIG. 1 can be used. The end electric supply with cord attaches to the end of standard track such as Halo™ track. The power cord connects to a wall receptacle or other electrical power source.

A two-circuit track can also or alternatively be used, where track fixtures are electrically attached to one or more of the multi-circuit track's circuits and are controlled independently with the remote control. This exemplary embodiment can be used when existing tracks and other existing fixtures are wired for multiple circuits.

Another exemplary embodiment of the inventions allows track fixtures or devices that use different voltages, such as different voltage levels or A.C. and D.C. voltage. Track fixtures can use numerous different voltages and devices including 12V fractional motors, 24V fractional motors, 120V fractional motors and 240V fractional motors, either AC or DC, and the track lights used include 12V, 24V, 120V and 240V AC and DC. The power is stepped up and down by power controllers, converters or transformers.

FIG. 1 illustrates an exemplary embodiment of the present inventions in a residential or office setting including elements of the first preferred embodiment (track fans and track lights on a ceiling-mounted track controlled by a remote control with electronically programmable controllers. Track fans 2 and track lights 3 are structurally and electrically connected to a one circuit electrical supply track 1, that is electrically connected to a one circuit power supply with a floating canopy electric supply 5, or electrically connected to a power supply using an end electric supply with power cord 6 inserted into a wall receptacle. The energy efficient (low wattage) track fans 2 are remotely turned on and off by pushing the remote fan push button 41 on the hand held remote control 4, independently from the energy efficient track lights 3 (that use compact fluorescent bulbs and/or LED bulbs) that are remotely turned on and off by pushing the remote light push button 42 on the hand held remote control 4. The hand held remote control 4 can be temporarily placed on any cool, dry surface or temporarily placed in the remote control holder/charger 44 that is mounted to a wall switch, wall or other vertical structure and used similar to a wall switch. Remote control holder/charger 44 can be used to recharge remote control 4, so as to avoid the need for replacing batteries. In addition, remote control holder/charger 44 can have a page control to allow remote control 4 to be paged to locate remote control 4.

Remote control holder/charger 44 can also include a screen such as an LED or touch-sensitive screen, to allow system configuration controls to be presented to a user and input into a programmable selector and programmable controller. In one exemplary embodiment, remote control holder/charger 44 can query all track fixtures, and can display a list of available fixtures with user-selectable controls to assign fixtures to a group, to a remote control selector, or other suitable controls. Remote control holder/charger 44 can have a “test” feature to allow each associated fixture to be momentarily operated to confirm its identity on the display. Remote control holder/charger 44 can provide controls for setting light levels, fan levels, light orientations and fan orientations, such as where the base of the track fan or track light includes positioning servo motors that allow the orientation of the track fan or track light to be controlled.

Swivel 24 can include one or more servo motors to allow the horizontal orientation of track fan 2 to be controlled. Fractional motor 21 can include one or more servo motors to allow the vertical orientation of track fan 2 to be controlled. Support arms 25 provide improved stability for motor 21 as compared to a single mount support, due to vibrations that are generated by blades 22, and prevents the fan assembly from experiencing vibration or transferring vibration to other track fixtures, which can result in damage to the track fixtures and potential disengagement of the track fixtures from the track. Motor 21 and blades 22 are likewise balanced so as to provide no net horizontal or vertical force to support arms 25 at rest or in motion, other than a net downward force due to the weight of motor 21 and blades 22.
